Error with logviewer portlet

[rayees80]

Hi,

First, we found the log viewer portlet very useful.

But yesterday, We came across the following error message while using logviewer.
Please advice...

Mar 22, 2016 4:53:36 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [default] in context with path [] threw exception
java.io.FileNotFoundException: /root/liferay-portal-6.2-ce-ga4/tomcat-7.0.42/work/Catalina/localhost//aggregate/https/html/portlet/journal/js/navigation.jsbrowserId=other&minifierType=js&languageId=en_US&b=file%3A%2F%2F%2F..%2F..%2F..%2F..%2F..%2F..%2F..%2Fboot.ini............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................&t=1458222788000_E_CONTENT_TYPE (File name too long)

Is it OK continuing using the portlet?

It is OK to continue using the portlet (the portlet is not the component causing that log content to be generated).
Do you see those log contents as well in your tomcat's catalina.out file?

It looks to me that someone tried to modify a liferay JS URL to send invalid URL parameters, you might have a look at your access logs to check.
